the height of the right trapezoid is smaller than the width of the limiting ring.

Further, the length of the lower bottom of the right trapezoid is less than or equal to the length of the tubular body.

Furthermore, the included angle between the oblique waist and the lower bottom of the right trapezoid is less than 45 degrees.

Furthermore, the connection between the oblique waist and the upper bottom of the right trapezoid adopts circular arc transition.

Furthermore, the longitudinal section of the elastic trapezoidal wing is wavy.

Furthermore, deformation compensation grooves are distributed on the left surface and the right surface of the elastic trapezoidal wing at intervals in a staggered mode.

Further, the section of the deformation compensation groove is arc-shaped, triangular or the combination of the arc-shaped and the triangular.

The pipe cap of the utility model adopts the embedded pipe end, thus avoiding the problem of easy falling off during transportation and installation; meanwhile, by means of the special structural design of the trapezoidal wings of the pipe cap, one pipe cap can be sleeved with all wall thicknesses and pressure specifications with the same outer diameter in the standard, the manufacturing cost of the pipe cap is reduced, and the pipe cap is more convenient to install.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1

Referring to fig. 3, a PE gas pipe end sleeving pipe cap comprises a tubular body 1 and a blocking plate (located inside the body and not shown in the figure) installed inside the tubular body in a sealing manner along the circumferential direction; the end part of the outer end of the tubular body 1 extends outwards along the radial direction and is provided with a limiting ring 2; a plurality of elastic trapezoidal wings 3 extending axially are arranged at intervals on the periphery of the outer wall of the tubular body 1 (can deform within a certain range when stressed).

The elastic trapezoidal wings 3 are of a right-angled trapezoidal structure, the lower bottoms of the right-angled trapezoids are fixedly connected with the outer wall of the tubular body 1, and the length of the lower bottoms is slightly smaller than that of the tubular body 1; the straight waist of the right trapezoid is fixedly connected with the limiting ring 2, the inclined waist points to the inner end of the tubular body 1, and the height of the right trapezoid is smaller than the width of the limiting ring 2; the included angle between the oblique waist and the lower bottom of the right trapezoid is less than 45 degrees; the connection between the oblique waist and the upper bottom of the right trapezoid adopts arc transition, so that the abrasion of the gas pipe during insertion can be prevented.

When the gas pipe cap is used, the inner end of the gas pipe cap is inserted into the end portion of the gas pipe, the elastic trapezoidal wings 3 deform and clamp the pipe wall under the constraint of the pipe wall of the gas pipe, then the gas pipe cap is continuously pushed to enable the end portion of the gas pipe to be tightly propped against the limiting ring 2 at the outer end, and the gas pipe cap is installed in place at the moment. Because the elastic trapezoidal wing 3 has certain deformability, the elastic trapezoidal wing can adapt to pipes with various inner diameters, and is particularly suitable for pipes with the same outer diameter and different thicknesses and with similar specifications.

Example 2

Referring to fig. 4, a PE gas pipe end sleeving pipe cap, based on the structure of the embodiment 1, the longitudinal section of the elastic trapezoidal wing 3 is wavy.

Example 3

Referring to fig. 5, in the pipe cap sleeved at the end of a PE gas pipe, on the basis of the structure of embodiment 1, deformation compensation grooves are alternately distributed on the left and right surfaces of an elastic trapezoidal wing 3, and the cross section of each deformation compensation groove is an arc shape, that is, an arc-shaped deformation compensation groove 4.

Example 4

Referring to fig. 6, in the pipe cap for sleeving the PE gas pipe end, on the basis of the structure of embodiment 1, deformation compensation grooves are alternately distributed on the left and right surfaces of the elastic trapezoidal wing 3, and the cross section of each deformation compensation groove is triangular, that is, a triangular deformation compensation groove 5.

The working process of the embodiments 2 to 4 is the same as that of the embodiment 1, except that the elastic trapezoidal wings 3 are designed to be wavy or the deformation compensation grooves 4 are added, so that when the elastic trapezoidal wings 3 deform, the wavy design and the deformation compensation grooves 4 are more convenient to deform, and the adjustment and compensation effects on the whole deformation can be realized.

The present invention is not limited to the above-described embodiments, and various changes can be made within the knowledge range of those skilled in the art without departing from the spirit of the present invention, and the changed contents still belong to the protection scope of the present invention.
